Abstract

An input port (2) of an electronic computer (4) of a motor vehicle includes: i) a plurality of pull-up loads (230a), each pull-up load being coupled to a power supply line (21) and to an input line (20) and including at least one transistor (231a) forming a current mirror with a first current reference module (232a), and ii) a plurality of pull-down loads (230b), each pull-down load being coupled to a ground line (22) and to the input line (20) and including at least one transistor (231b) forming a current mirror with a second current reference module (232b). Each pull-up load and each pull-down load includes a switch (233a, 233b) and the input port is configurable by ordering the closure or opening of each switch. An input circuit (3) including at least one input port and an electronic computer of a motor vehicle including the input circuit are described.
